Fix perf of DateTime.Now on Unix

Profiling DateTime.Now on Unix shows that a lot of time is spent in GetPreviousAdjustmentRule and AdjustmentRule::Equals. Instead, it is safe to use ReferenceEquals, which increases the performance of DateTime.Now and other time zone operations on Unix.

Fix VSO bug 405852.

This bug was due to a mismatch between the semantics of the FP modulus
operator as specified by ECMA-335 and as implemented by value numbering.

ECMA-335 requires the following behavior for FP modulus:
- If the divisor is 0 or the dividend is not finite, the result is NaN
- If the divisor is not finite and is not NaN, the result is the
  dividend.
Value numbering, however, simply used `fmod`, which does not have these
semantics. This change implements the required semantics in VN.

Get rid of "#if FEATURE_RANDOMIZED_STRING_HASHING" in shared partition. (dotnet/coreclr#10851)

Since CoreCLR defines it (for now) and CoreRT doesn't, let's not have
"#if's" on this in shared code. It just creates confusion.

The only ones are in StringComparer.cs and fortunately, they are quite
expendable as...

1. It's only purpose is serialize Hashtables and Dictionaries in
   a way that CLR 1.1 can deserialize them. We don't care about that in
   .NET Core.

2. In CoreCLR as of today, this infrastructure is not changing the serialization
   blob one iota since all the GetEqualityComparerForSerialization() methods
   return "this."

So this removes the appearance of downgrading the comparers to non-randomized
versions for serialization purposes (and yes, we could go on and remove
all the other "let's do it for Everett and RTM" stuff in Hashtable.cs, but
I want to keep this PR on topic. Hashtable.cs is not going to be imported
into CoreRT so it's low priority for me.)

Fix jit32 Perf testing

In the CI, we were moving compatjit.dll into the Products directory
instead of the core_root directory, so the jit32 compatjit.dll was not
being picked up by the build. This change moves the nuget logic to before
we run runtest.cmd generatelayoutonly, so the jit32 compatjit.dll will be
moved to the core_root directory along with everything else.
